Terrence O'Brien is the Verge’s weekend editor. He’s covered the tech industry for over 18 years and knows a thing or two about synths.

It took long enough, but now LA rapper Fenix Flexin appears to have admitted using AI for the 80s synth pop-themed song “Rubberz.” His comments follow the producer Medasin’s videos claiming that an AI tool called Treblo (formerly Sonauto) was used to make the song, and the company releasing an AI detector that identifies it as Treblo AI-created.

In a reply to a comment pointing out that Tyga admitted to relying on AI for his own controversial ’80s-influenced album $tarface, on one of his Instagram posts, Fenix said:

never said I didn’t use AI , i said it had nun to do w recording process . I didn’t even know what da app was till we mixed it and erbody started commenting . ain’t nothing wrong w using new technology as a tool keep up w the times or get left behind

The comment insists he never denied using AI, but last month on Hot 97’s Mornings With Mero when asked directly about AI use by interviewer Kazeem Famuyide, he stated clearly that there’s “no AI on it.”

He’s repeatedly gone out of his way to try and dispel the AI allegations publicly since the song was released, despite what he says now. Fenix and his team have posted what they claimed were clips of the recording session files, popped into the comments to insist the song was made by two humans recording in his living room with “pro tools auto tune and some reverb,” and said he’s actually singing in clips where it looks like he’s lip syncing.
